IMPROVEMENT IN' ELEvAToRs.

The Schedule referred to in these Letters Patent and making part nf the same.

.To all 4whom 'it may concern Be it known that I, CnARLns 1t. FonnMAN, of West Branch, in the county ofOneidaand State of New York, have invented a new and useful Improvement in steadfast and Traveling Automatic Hay-,Fork Pulley; .and l do hereby declare that the following is a full, clear, and exact description thereof', which will unable others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a side view of my improved machine, part being broken away to show the construction.

'Figure 2 is a detail'vertical section of the same, taken through the line a: a" of tig. l.

Figure 3 is a detail vertical section ofthe same, taken through the line yy, iig, 1.

Figure 4 is a perspective view of the catch and its pivoted frame.`

Figure-5 is a detail sectional View, taken through the lille z z, iig. 1.

Similar letters of reference indicate corresponding parts.

M v invention has for its object to furnish an improved device for carrying a loaded h( y-fork or other weight from 'the place where it is hoisted to the place where it is to be deposited, which shall be so constructed and arranged as to h'e held steadily in place until the fork or other weight has been raised, and

:which will then detach itself automatically and carry the said weight back to the place where it is to be deposited, and which shall be at the same time simple in construction and easily operated; and

' It consists in the construction and combination of the various parts of the device, as hereinafter more lully described.

A- is themain frame of the carriage, in the middle part of which is pivoted the grooved pulley B, around which the hoisting-rope O passes.

Upon the upper' part of the frame A are fol-ined two loops, a', in which are pivoted two grooved pulleys or wheels, D, which roll along the wire lor rod E as the can-inge is drawn back and forth.

The loops a' are made open upon their alternate sides, as shcwn'iu figs. 1 and 2, so that the carriage may be conveniently placed upon and removed from the .wire E when desired.v This enables the carriage to be readily shifted from one to"anothcr of several rods or wires stretched in different parts of the barn,l

or moved tiom one barn to another,.without its being necessary to slacken or take down the rod o1' wire E.

when the sa'id hooks-are hooked upon their catches, move up beneath the rod or wire E, so as to keep the wheels D in place upon the rod or wire E, however 1n uc'h the said carriage may be moved out of plumb laterally.

H is a short tube, through which the hoisting-rope C passes, and the-lower end of .which is made fiar-ing, asshown in tig. 1.

The upper end of the tube H is securely attached to the plate I, one end of lwhich is perforated to receive the arms J, to which it is adjustably secured by nuts, as shown in ligs. 1 and 2.

The other end ofthe plate I'is perforated, to receive the lower ends of the rods K, to which it is sccured by nuts, as shown iugs. 1 and 3.

The rods K pass up throughl guide-holes in the frame A, and their upper ends are connected above the frame A. by a cross-bar, L.

M isa plate, sliding in guides upon the upper side of the plate I, and the forward end of which is notched, as shown in tig. 5.

The rear end of the plate M is perforated, to 'receive the lower end of the lever N, which is pivoted to a support, O, attached to the rods K.

P is a spring connected with the rods K, and which presses againstthe upper end of the lever N.

Q is a catch pivot-ed to the frame IR, and the forward or notched end of which projects in front of the said frame It.

The forward or projecting end of the catch Q is beveled cti', as shown in lig. l, so that, when the carriage is drawn back against the said catch-trame, the catch Q may catch upon the upwardly-projecting end ofthe end bar of the frame A.

' The end bars or plates of the catch-'frame 1t project upward, and are notched upon their side edges to received the rod or wire E, to which they are secured by hooks S, covering the notches in thesaid bars,

lhe frame R is kept from being drawn forward upon the wire or rod E by a collar, e', formed upon or attached to .the said wireor rod E. This construction enables the catch-trame R to swing' latcrallyas the frame A swings;

The lower end of the front end bar of the frame R projects downward, as shown in 1, for the upper cud of the lever N to strike against, to operate'thel said lever.

T is a cylindrical block, of such a size as to pass freely through the tube H, and upon the upper end of which is formed an eye for lthe attachment of the hoisting-rope C. Upon the lower end of the block T is also formed aneye' for the attachment" of the hay-fork or other weight to be hoisted.

Around the block T, a little below its upper end, is

formed a neck to receive the notched forward end of the sliding plato M.

U is a pin, passing through the block T at sucha distance below the ,neck formed upon the said block, that, when the said neck is in position to receive the sliding plate M, the projecting ends of the pill U may be resting against the lower end of the tube H.

The rope C, after passing over the pulley B, passes around guide-pulleys attached to thc-frame of the buildthe wire or rod E, and usually without any further assistance from the draft.

At the instant the fraaie A springs away from the.

catch-traine R, the lever N is released, and the elasticity ofthe spring P operates the said lever to push the sliding plate M forward, so that its notched forward end may embrace the neck ot' the block Tand Y support the fork or other lweight. until it has been car- 4ried to the place where it is to be deposited. Then,

by operatinglhe trip-ropethe hay'fis discharged.

The trip-rope] prefer to make long, one end being attached to the tripping device, and the other end to the carriage A, so that the. same rope may be used for discharging the load and ibrdrawing the carriage back-to its place.

the. carriage is drawn hack the catch Q catches upon the frame A. Atthe same time thc upper end of the lever N strikes against the front end bar of the catch-.frame R, which operates the said lever and withthe block T, allowing the said block and its attached fork to descend for another load.

Having thus described my invention,

Patent- 1. The combination of block T U,'guidetnbe H, plate I, arms J, bars or, rods K, and cross-bar L, with the frame A of the carriage, and with the catch Q and catchframe R, for the purpose of disengaging the said carriage from the said catch, substantially as herein shown and described.

2. The combination ot" the spring P, lever N, `and sliding notchedplate M with-the block T U, plate I, rods K, and catch-frame It, for the purpose of supporting and releasing the fork or other work automatically, substantially as herein shown and described.

3. Detachabl y connecting and pivoting the carriage frame A to the wire or rod 'E by means of the open loops a', grooved wheels'D, hooksF, and pins G, substantially'as herein shown and described and for the purpose set forth.

4. .Detachably connecting and pivoting the catoliframe R tothe wire or rod E'by'means ot' the. notched end bars of said frame, the hooks S and collar e', substantially as herein shown and described Aand for the purpose set forth.

The above specification of my invention signed by me this 27th day of January, 1870.
